I'm looking to get a new wheelset and I'm thinking about the DA 9100. But there just isn't a whole lot of information and/or review about these wheelets. I'm looking to get the Dura Ace C60 tubular, rim brake version.

All I know so far is that these rims will be 28mm wide, and the rear hub uses Shimano all new Sylence tech where it has zero resistance while coasting, and it would make loud sound while coasting either. This interest very much.

anyway, has anyone got anything to add? Please do so

this page has good info on the new 9100 wheelsets
New C40 and C60 Dura-Ace 9100 and 9150 wheels get wider and faster | CyclingTips

"Shimano makes big aero claims for its designs, and hints that this is its biggest investment into aerodynamically designed wheels to date. The chart we were shown claimed that the new C40 and C60 tubulars saved two and 16 watts, respectively, when compared to the current 9000-series C50.
...
The long standing C24 is mostly unchanged for the next generation, with a marginal improvement in drive rigidity through wider hub flange spacing "

So C60 saves 16 watts over C50? I think I'm disappointed considering this is Shimano's biggest investment in aerodynamics!

What about the new rear hub? What about the ride and feel characteristics of the new wheelset? Nothing mentioned about it.

Always remember that Shimano made a big investment in proving that Bio-Pace chain rings were going to save us all a lot of energy. Spending money does not automatically equal quality engineering.
